Widgets Slicer wish list

Angle measurement [Done]

• A 3D representation to the angle widget has been added. The following were added to support this:
  • vtkAngleRepresentation3D.cxx/h
  • vtkArcSource.cxx/h
  • TestAngleWidget3D.cxx
  • TestAngleWidget2D.cxx
• Bug fix: unnecessary renders were removed from the angle widget. This somehow went unnoticed in the 2D case, possibly because the data being rendered is fairly small.

Distance measurement widget [Done]

• Line Widget extended to support optional text annotations indicating the distance between its end-points. This should suffice to measure distances between 2 points in 3D.

Picking issue with widgets [Done]

• Bug picking implicit plane widget.
  • Note to KK: Look at SlicerPlaneSWidget.tcl:75

Updating Fiducial list to vtkSeedWidget [Working on it]

Notes from talking with Nicole, Oct 7/08

Features needed:

• Ability to set properties per seed
• Ability to associate a label with a seed.
• Label visibility can be toggled on/off
• Ability to associate (optionally) a note with a seed (Ron's request)
• Glyps for seed shape
  • 2D
    • All the ones in vtkGlyph2D
    • StarBurst2D,
  • 3D
    • Sphere3D
    • Diamond3D
• Nicole to check if transform is applied to the fiducials in slicer registration. Really bad idea to do so with widgets.
• Constraints on fiducials
  • Constrained to an image actor as in File:ImageActorConstrainedFiducial.avi

Affine widget

• Mega widget (will take time)
• 6 degrees of freedom.

Live wire widget

• Live wire widget for the editor
• Exists in VTK HEAD Sep 08. Upgrade from VTK 5.2

Contour widget (just a wish, not urgent)

• Use case: Pick a series of models to place in a hierarchy
• Lasso around a bunch of objects in 3D

VTKEdge

• Steve and Will to talk about VTKEdge, licensing etc.
• Paintbrushes in VTKEdge
• GPU ray caster
